[Adjustment procedure]
1) Using the remote controller, transmit the “monitor adjustment process” code.
2) Set the 6th point to the specified gradation level. With the strongest color being fixed,
turn down the R, G and B settings to their reference levels.
3) Set the 5th point to the specified gradation level. Correct the G setting (800 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
4) Set the 4th point to the specified gradation level. Correct the G setting (480 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
5) Set the 3rd point to the specified gradation level. Correct the G setting (312 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
6) Set the 2nd point to the specified gradation level. Correct the G setting (232 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
7) Set the 1st point to the specified gradation level. Correct the G setting (184 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
8) With the MSET0003 command, write the adjustment values and turn off the AC
power.
* Initial R, G and B settings at point 6: Gradation level set at 928
* Initial R, G and B settings at points 1 thru 5: Corrected G setting at each point
(This is because the adjustment is made to achieve the same remainder of RGB setting /
4 at each point.)
